RAlLWAY-BUFFER ARRESTER.

SPECIFICATION forming part of Letters Patent No. 555,273, dated February25, 1896.

Application filed December 2, 1895. Serial No. 570,738. (No model.)

To all whom, t may concern.'

Be it known that I, J OHN A. IVEBER, a citi- Zen of the United States,residing at Chicago, in the county of Oook and State of Illinois, haveinvented certain new and useful Improvements iu Railway-BufferArresters, of which the following is a specification.

My invention relates to that class of apparatus which is located usuallyat the end or termination of a railway-track and employed for thepurpose of arresting the progress of a train or car upon the track,which is moving toward the end thereof.

. The object of myinvention is to provide an apparatus for this purpose,which shall be capable of resisting the strain imposed thereon by theforcible impact of the moving car and to accomplish this result by anapparatus which shall be simple in construction and of minimumcheapness.

To this end my invention consists in a stationary bilder-post, which isheld in a vertical position intermediate between the rails of the trackby means of any suitable stay-rods or the like, and a movable orswinging bufferpost which is pivoted or hinged to the stationary post,the latter receiving the initial impact of the moving car or otherobject and distributing the strain along its length, the stationary postalso co-operating conjunctively with the hinged post in order to resistthe strain of the shock, means being employed for causing the hingedpost to normally assume a receptive position after receivingthe impactof the moving object.

My invention consists in certain other features hereinafter to beparticularly described, reference being had to the accompanyingdrawings, in which* Figure l is a perspective view of a section ofrailway-track, showing my device for arresting the movement of a trainarranged in position. Fig. 2 is a vertical section through thebuffer-posts, showing the device for normally causing the movablebuffer-post to resume a receptive position.

In carrying out my invention I provide the stationary buffer-post A,which is held firmly in its stationary position by means of theencircling band A2, and stays or stay-rods A2, extended and fastened tothe longitudinal rods A, which are secured to the track. This stationarybuffer-post A may be designated as the auxiliary buffer-post, as thesame reinforces or supplements a primary buffer-post, about to bedescribed, which receives the initial or lirst shock of the moving carupon the track.

The primary buffer-post is designated at B and also has an encirclingband B2, this buffer-post B being hinged to swing upon the buifer-post Aby means of the hinged connection D between the two encircling bands A2and B2.

Extended loosely through the bu ffer-post A is a pull-rod H, which issecured at one end to the lower portion of the buer-post B and has ahead H2 at its other end, a spring J being disposed about said pull-rodH and located between the head H2 and the rear side of the buffer-postA.

At the points of impact on the upper faces of the buffer-posts A and B,I secure suitable rubber blocks K and K2, which serve as cushions.

It is now apparent from the foregoing description that the spring Joperating upon the pull-rod H normally holds the lower end of thebuer-post I3 in such a position as that the upper end thereof isadvanced into a position to receive the forcible impact of the car orother movable objects advancing toward the end of the track. .XVhen themovable object forcibly impacts against the upper end of the buffer-postB said upper end receives the initial strain of the forcible impact andin traveling rearward under such influence causes its lower end to moveforwardly in an opposite direction by reason of the hinged connection atB2. Owing to this forward movement of the lower end of the buffer-post Bthe pullrod Il and its head H2 are also drawn forwardly, thuscompressing the spring J disposed between said head H2 and thebufferpost B. It is thus evident that this spring J, in offering aresistance to the rearward movement of the upper end-of the buffer-postB, serves in conjunction with said rearward movement to relieve theshock of the forcible impact which the device as a whole must receiveand relieves the strain of the shock to a considerable extent before theupper end of the buffer-post B strikes against the stationarybuffer-post A. Therefore, by means of IOO the movable buffer-post thestrain of the shock which ordinarily is imposed immediately upon thestationary buffer-post is relieved by the preliminary traverse of saidmovable buffer-post and the resistance of the spring, Which latter alsocauses the movable bufferpost to resume a position in which again toreceive the forcible impact of an object such as a car moving along thetrack.

Having thus described my invention7 What v I claim as newr therein, anddesire to secure by Letters-Patent, is-

l. In an arresting device for railway-tracks the combination with astationary buier-post held between the rails of a movable buierposthinged to the stationary buffer-post and adapted to receive thepreliminary strain of the shock from forcible impact and relieve saidshock by a traverse of the movable buffer-post thereunder.

2. In an arresting device for railway-tracks the combination With astationary buffer-post held between the rails of a movable bufferposthinged to the stationary buffer-post and adapted to receive thepreliminary strain of the shock from forcible impact and relieve saidshock by a traverse of the movable buffer-post thereunder together witha resisting device acting in opposition to the movement of said movablebuier-post.

3. In an arresting device for railway-tracks the combination with astationary buffer-post held between the rails of a movable bufferposthinged to the stationary buffer-post and adapted to receive thepreliminary strain of the shock from forcible impact and relieve saidshock by a traverse of the movable buffer-post thereunder together witha pull-rod and spring acting in opposition to the movement of themovable buler-post and adapted to return the same into a position toreceive another impact.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN A. IVEBER.
